What to Include in a Construction Proposal (Complete Checklist 2026)

Everything a construction proposal must include to win bids and protect contractors legally — scope, exclusions, timeline, payment terms, and more.

A proposal isn't just a price sheet — it's a legally relevant document that defines what you agreed to build and for how much. Missing sections don't just lose bids; they lose disputes. Here's the complete checklist.

Pre-proposal elements

  • ☐ Company letterhead with logo, license number, and contact info
  • ☐ Client name, address, and contact info
  • ☐ Project address (may differ from client address)
  • ☐ Proposal date and "valid until" date (30 days is standard)
  • ☐ Proposal number (for your records and change-order referencing)

Scope of work

  • ☐ Specific description of all work to be performed
  • ☐ Room-by-room or zone-by-zone breakdown if applicable
  • ☐ Material specifications (brand, grade, color if relevant)
  • ☐ Finish quality specifications ("smooth finish," "texture to match")
  • Exclusions — explicitly list what is NOT included (this is critical)

Pricing

  • ☐ Itemized line items (not lump sum)
  • ☐ Materials and labor shown separately or as a line-item total
  • ☐ Sales tax treatment (included or excluded — state clearly)
  • ☐ Allowances for client-selected items (e.g., "tile allowance: $5/sqft")
  • ☐ Total contract price

Timeline

  • ☐ Estimated start date (or "within X weeks of signed contract")
  • ☐ Estimated completion date
  • ☐ Conditions that could affect timeline (permits, client decisions, weather)

Payment terms

  • ☐ Deposit amount and when due (typically 20–33% on signing)
  • ☐ Progress payment schedule tied to milestones
  • ☐ Final payment amount and trigger (completion and walkthrough)
  • ☐ Payment method accepted (check, card, ACH)
  • ☐ Late payment terms if applicable

Legal and protection sections

  • ☐ Change-order procedure ("changes require a written, signed change order")
  • ☐ Warranty terms — duration and what's covered
  • ☐ Insurance certificate reference (or attach a COI)
  • ☐ License number
  • ☐ Dispute resolution clause (optional but valuable)

Acceptance

  • ☐ Client signature line
  • ☐ Contractor signature line
  • ☐ Date of acceptance
  • ☐ Online sign link (closes 30–40% faster than paper)
